This feature uses a number of thermostats, a sophisticated central controller, and a series of dampers that control airflow to deliver different amounts of heating or cooling to different parts of the home. The larger the home, as a rule, the more useful zoning is. That's especially true if sections of the home have different heating or cooling requirements, because of wide variations in the number or type of windows, for example. But contractors we interviewed said that furnaces connected to zoned ductwork generally require more repair.

Among the leading ways to prevent a breakdown and make sure it runs like a lean machine is with yearly scheduled tune-ups on your furnace. Just like any mechanical equipment, the useful life of a furnace will be enhanced with preventive maintenance, by ensuring that all the elements of the unit are running efficiently. In addition, regular cleanings can help pinpoint concerns before they become big problems and you end up paying emergency rates on a cold winter night. Plus, because furnaces burn fuel to make it hot, it’s important to inspect all the various pieces to ensure there aren’t any ruptures or leaks that could impact the safety of your family. Taking the time to schedule a tune-up, even when it’s not making that odd rattling noise you’ve been ignoring, will save you time, stress, and money throughout the heating season.

Dirty furnace filters are one of the most common causes of a furnace failure. A dirty furnace filter can limit the airflow through your furnace and cause it to overheat. If you suspect a dirty air filter, change the filter, press the reset button (if your furnace has one) and see whether your furnace begins to emit heated air. Change your furnace filters regularly — pros recommend changing them once a month — to ensure that your furnace continues to work properly. Unaddressed, dirty furnace filters can cause extensive, and expensive, damage to your home’s heating system.

Mechanical air filters trap pollutants by filtering them out of the air as it passes through. Electronic air cleaners pull air in, give the pollutants in that air a static charge, and trap those pollutants on an oppositely charged surface. By working with a qualified professional you can rest assured that you have the right air filtration system in Seattle, WA.

If you pull out your home’s air filter, hold it up to a light. If you can’t see light coming through it, it’s most likely been a while since your last heating service, and likely time to get a new one. If it’s a simple disposable air filter, just replace it with a like-size new one. It’s also a good idea to write down the date you installed the new filter, so you know how old it is next time it needs to be replaced. Check the filter packaging to see how long the new air filter is supposed to be used.
To be sure of correct sizing and a proper installation, choose a reputable contractor who will take the time to calculate your heating needs according to an industry standard such as in "Manual J HVAC Residential Load Calculation" of the Air Conditioning Contractors of America. Such calculations take into account the climate and the size, design, and construction of your house. Once the furnace is installed, maintain it regularly according to the manufacturer's recommendations. Our survey helped to confirm this advice. When we asked about the most common reasons for service calls for furnaces, contractors cited human error, inadequate maintenance, for example, or improper installation, twice as often as defective equipment. Read our frequency of repair report for which brands or the most and least reliable.
The cost of a new furnace might make you balk at first thought, but with modern manufacturers offering an extremely diverse range of options with varying AFUE ratings, optional accessories, and more, there is a furnace to meet any budget! It’s just important that you work with the right service team and experts that will work with you rather than try to “sell” you.

When your heating and cooling system stops working, you need the help of a reliable, experienced, local service professional that can diagnose the problem and repair your air conditioner or furnace at a fair price. You can count on The Home Depot's licensed and insured heating and cooling professionals for all your heaters, air conditioning units, and any ventilation needs.

If your furnace needs to be repaired, you’ll want to find a qualified heating, ventilating and air conditioning (HVAC) repair technician. Each state has its own licensing requirements; some require all HVAC technicians to have an HVAC license, while others only require someone operating an HVAC service and installation company with employees to hold a contractor’s license. For example, in Alabama, the Alabama Board of Heating Air Conditioning, and Refrigeration Contractors regulates licensing, while in Kansas there is no state regulatory body and HVAC licensing can vary by region. For simple furnace repairs like changing out a filter, a trusted handyman can probably handle the job, but a trained professional should be hired for tasks like replacing a gas valve, installing a new inducer fan motor or other critical furnace repair jobs that involve dealing with gas leaks or other dangerous conditions.

High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
